You should say “Thank you”when someone       you the salt on the table, when someone walks aside to let you       in a corridor (走廊), when someone       ahead of you keeps the door open       you, when someone says your work is well       or you have bought a nice thing, or your city is very beautiful.
“Thank you”is       not only between strangers or new friends, but also between old friends, parents and children, brothers and sisters, husbands and wives. Parents often tell      children that they should say “Thank you”in answer to a kind word or act when they are only four      five years old. Perhaps that’s      almost everyone has got this habit.
